Safe 'Doors and the like, of 'which the following is-a specification. 3 v p My invention relates to improvements 1n emergency bolt looks, more especially to a bolt lock where ,a spring is used to throw theloc king lug into its locked position when the combination lock which is on the vault door is broken off. k

One object of my invention is toprovide an emergency bolt lock, that will work by automatic action and look all the bolts on the vault, or safe door when the spindle of the combination lock which isonthe' vault or safe door has been driven in orbroken off. Another object of my IDVGIltlOIl 1s to provide an emergency bolt lock, that cannot be jarred loose and lock the vault or safe by the closing of the door. I Q

Another object of my invention is to provide an emergency bolt lock, that. is cheap in construction and 'canbe applied to any style of vault or safe :dooryby unskilled labor. I v r Another object of my invention isto provide an emergencybolt lock, that can be held firmly unlocked and looked 311113011131]? ically when the combination lock which is on the vault or safe door has been-broken into.

l Vith these and other objects in view, my invention consists of the following novel construction and arrangementof parts, to be hereinafter described and claimed, reference being'had to the annexed drawings forming part of this specification and to the figures of reference marked thereon; Figure 1 is. an inside viewof a vault door showing the invention attached.

m1 locking bolts ofthe door, F. the tie plate for the locking bolts'E, Caltheangleiron on the inside of the door for supporting the horizontal locking'jbolts E, H the door frame, 1 the threaded bolt, 2 the spring, 3

and 3' the tension nuts, for. holding the spring 2 in tension, 2 and 2 the nuts for securing the. bolt l tothe angle iron G, 4 thelocking lug, 5 abracket-mounted on the bolt 1 for supporting the trigger '7, 6 and t3 the nuts for holding the bracket 5 firmly 1n place, the trigger for holding the lock wire extending to the combination lock ing lug .4 in its unlocked position, 8 the casing D, 9 the wirethat is-attached to the p stem 2320f the handle 33; the wire 9 is only used when thehandle133 is of old style make and is secured thereto by the nut on said handle (notshown); 10'is the rivet forse- J curing the trigger to the bracket 5. v

I Iaving thus described the partsofmy invention, I will now endeavor to illustrate the operation and assembling -ofsame.

I start by takingthe bolt 1 and screw on the nuts 3, 3 and 27. Now I place onto the bolt 1 the spring Zand placethe end 12 of L said spring into the hole 11 of the nut 3. Now I place onto the bolt 1 the locking lug 4: and place the end- 14 of the spring 2 into the hole 13 in the locking h1g4. Now'I place on the unto Now the bracket 5 and the not 6'. Now I take the trigger'7 and place it intothe-notch 30 of the bracket 5 and pivot it thereto by means of'the rivet N owl I attach the wire 8 t0 the trigger 7 at 15, also attach'the wire 9 when necessarya The invention is now ready to be applied to the vault door.

v In applying my invention toa vault door, I first drill a hole '17 into the angle iron G at any desired place-.. Now I place the end 16 of the bolt-1 into the hole 17. ,Now I place ontothe end 16the nut 2' thentighten up the nut 2" against the angle iron G.- I flow I adjust the locking lug t so it will justclear the'back of the tie plate F when thebolts E arein their locked position by turning the-nutsfi and 6'. To increase the tension of the spring 2 I turn the nut 3 on the bolt 1 till the required tension has been secured. To preventthe nut 3'from turning, I tighten the nut 3 against the nut 8. Now

Itake the wire8 and secure it over the back i of the combination lock casing D and the back of thecombination lock 19then I secure the end 20 tothe' door bymeans of a screw, which is screwed into the door. In

the. event that-the wire 9 is to be used I attach one end to the hole in the trigger 7 and the other end to the'inner end 32" of the handle 33. To set the locking lug 4 into'its unlocked position so it will be ready tension of thespring 2; In the event that the combination-mechafor use, I place it into a vertical. position and place the trigger 7 back of the lookinglug 4' as shown. The locking lug 4 is held firmly against the: trigger7 by the nisin istamperedwith in any way by unauthorized persons, such as burglars, who undertake to enter the vault by breaking through the combination lock and driving in the spindle which pushes off the back of the combination lock 19, thus causing a pull on the wire Swhich in turn lifts the trigger 7 into the position as shown by dotted lines 23 Fig, 4, thus-releasing the'locking h1g4 and 8 by"drivingfin the 32' of the allowing 'it to be thrown into the position as shown by; dottedlines 24 Fig. 3. In the event 3 0 that the wire 9'isvto be useditwill operate. the trigger' 7 in the same manner as the wire handle 33. a 1

After thesafe door has beenclosed and the F locking lug 4 has been thrown into its looking position and I wish toopen the door,.I

drill a hole intojthe face of the door just above the locking in '4' and then insert a wire loop into the hole ajnd'loop it'over the end '22 of the lockinglug 4 and then pull the locking lug14 back into its unlocked positionas shown in Fig. 3, and then turn the handle 33 and the doorwill come open.

"The location of the hole to be drilled into the tace of the door, is taken by measure merit by the'par'ty' who placeslthe bolt onto the door.

The above principlesare also applied to a safe when the bolt: is to beapplied.
